Specification forming part of Letters Patent No. 168,554, dated October 11, 1875; application filed July 30, 1875.

To all whom it may concern Be it known that I, EBENEZER BLACKMAN, of the cityof Brooklyn, county of Kings and State of New York, have invented a new and useful Improvement in Gas-Burners; and I hereby declare that the following is a full, clear, and exact description of the construc- Y tion and operation of the same, reference be- 'quantity of gas passing through it to suit the particular necessities of the location of the burner; and the object of the present invention is to prevent a person from burning more gas than will pass through one or more adjustable openings, permanently secured by an external spring;slide or regulator, or one that cannot loe rembxled/ for the purpose without using a nipper or its equivalent.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

It consists, substantially as hereinafter described and specified, in the application and use of a spring-slide or regulator, placed on or upon an inner tube, having one or more holes in its sides, said tube rising from the base of the burner, and having its upper end closed, as shown in Fig. l. The spring-slide or regulator is usually made of spring metal, tubular in form, with one side open, as shown at Fig. 3, and is operated by sliding up or down on the inner tube, and exposing one or more of the holes. Each hole represents a given quantity of gas under the ordinary pressure. j

It will therefore be evident that the outlet for the gas can be adjusted with perfect accuracy and facility without the parts becoming impaired by friction in use, and requiring only that the external burner C, which covers. the same, be removed for the purpose, and afterward replaced. The spring-slide or regulator will adjust itself to the size of the tube, and always be tight.

In the drawings, A is the base of the burner, and B the inner tube, with closed top on the same; C, the external burner, and D the springslide or regulator, which tits the tube B. The base A is tubular throughout nearlyits length, the upper end being closed, and a screwcut in its lower end, so that it can be secured to the usual gas-supplyin g pipe, as heretofore. It also has a screw cut on it, as shown at F,Fig. 2, for the purpose of securing the external burner C to the base A. lts upper part B is reduced in diameter, as shown in the drawings, and receives over or upon it the spring-slide or regulator D, which is retained in its place by friction. The tube B has one or more holes through its side, as shown at G, Fig. 2. The said holes are opened or closed byA moving up or down the spring-slide or regulator ll), as above described. y provided at its upper end with outlet holes or slits, in `the usual manner, and is made so as to leave a gas-space, E, around and above the tube B, and its spring-slide or regulator D, when secured gas-tight to the base A, which is adapted at F for the purpose, as shown vin Fig. l. It also has an inside screw, in the usual manner, and 'also an outside screw near the center of the burner, as shown at H, Fig. 1. The object of this outside screw is to screw on a globeho1der.

The operation is as follows: Theparts A, B, and C being secured and adjusted together as shown in Fig. l, and appliedto a gas-supplying pipe, 'it will be seen that the gas will flow through the burner with a copiousness proportionate to the pressure and the size of the outlet-holes; but if the spring -slidle or regulator be pressed down sufficiently to cover one or more of the holes in the base tube B, as shown in Fig. l, the current of gas flowing through the said holes will be reduced in proportion to the number of holes closed.

TheA improvement is simple, and can be cheaply and easily constructed and applied.

I do not claim, in a gas-burner, the com- The external burner G is bination ot'- an .adjustable hollow valve with a fallait-having @series of perforations otdifferont sizes in the same ihorizontal plane, the

saidvalve having a single perforation of' greater size than the largest perforation in the pillar; neither do I claim an adjustable gasburner, consisting of a tapered interior perforated cap and a tapered interior perforated tube, operating together, and inclosed in an external burner screwed permanently down upon a base or pillar.

Having thus fullyr described my improved
